Explanation:

This is the infertility corrective procedures, which involve the removal of the sex-cells of both male and female, the  fusion,(fertilization) of these, outside  the body  (in-vitro  fertilization), or isolation of a single sperm and fussing it with an ovum(intracytoplasmic sperm injection) to form  the zygote, and the implantation of the zygote back into the uterus, for the normal development  to embryo  and fetus.

This  procedure  may also involve the use of the Donor's egg or sperm, or frozen sex cells . Sometimes  If the  woman egg cells  are not receptive, the zygote can be  formed from her  husband  sperm, and carried  by another contracted woman called surrogate mother.However, if the zygote is formed from a  donor's egg the contracted woman is called a gestational mother.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
